Polyborus
''Caracara'' is a genus in the family Falconidae and the subfamily Polyborinae. It contains one extant species, the crested caracara; and one extinct species, the Guadalupe caracara. The South American Classification Committee of the American Ornithological Society has voted to again merge the two, retaining ''C. plancus'' as crested caracara. The taxonomists of the International Ornithologists' Union have also merged them. Appearance The crested caracara is distinguished by its long legs and medium size. The birds can reach a length of from head to tail. There are usually four points of identification of the caracara: strikingly white markings on the neck, the tip of both wings, and the tail. Along with their medium length, the caracara also has a wingspan of . When flying, the caracara is often noted to have a pattern on their underside that looks like a cross. Behavior The behaviors of caracaras are considered quite strange in relation to those of other falcons. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crested Caracara
The crested caracara (''Caracara plancus'') is a bird of prey in the family Falconidae. It is found from the southern United States through Central and South America to Tierra del Fuego. It was formerly placed in the genus ''Polyborus''. Description The crested caracara has a total length of and a wingspan of . Its weight is , averaging in seven birds from Tierra del Fuego.''CRC Handbook of Avian Body Masses, 2nd Edition'' by John B. Dunning Jr. (Editor). CRC Press (2008), . Individuals from the colder southern part of its range average larger than those from tropical regions (as predicted by Bergmann's rule) and are the largest type of caracara. In fact, they are the second-largest species of falcon in the world by mean body mass, second only to the gyrfalcon. The cap, belly, thighs, most of the wings, and tail tip are dark brownish, the auriculars (feathers surrounding the ear), throat, and nape are whitish-buff, and the chest, neck, mantle, back, upper tail coverts, crissu ...

Caracara Lutosa
The Guadalupe caracara (''Caracara lutosa'') or mourning caracara is an extinct bird of prey belonging to the falcon family (Falconidae). It was, together with the closely related crested caracara (''Caracara plancus''), formerly placed in the genus '' Polyborus''. It was also known as the quelili or the calalie. Distribution and taxonomy This species inhabited Mexico's Guadalupe Island until the beginning of the 20th century. The crested caracara is sometimes incorrectly referred to as "Guadalupe caracara", because the extinct birds were formerly considered a subspecies of the extant taxon. They were reinstated as a full species in 2000. History Described as "evil" and "vicious" by early observers, it was driven to extinction by a hunting and poisoning campaign led by goat herders on Guadalupe Island. As described by Edward Palmer: Conservation In 1876 the species was common throughout the island. However, in March 1897, only one bird was encountered, but additiona ...

Polyborinae
Caracaras are birds of prey in the family Falconidae. They are traditionally placed in subfamily Polyborinae with the forest falcons, but are sometimes considered to constitute their own subfamily, Caracarinae, or classified as members of the true falcon subfamily, Falconinae. Caracaras are principally birds of South and Central America, just reaching the southern United States. Unlike the ''Falco'' falcons in the same family, the birds in the five relevant genera are not fast-flying aerial hunters, but are comparatively slow and are often scavengers (a notable exception being the red-throated caracara). Species Distribution The caracaras are found throughout much of the Americas. The range of the crested caracara extends as far north as the states of Arizona, Texas, and Florida in the United States. In the Southern Hemisphere, the striated caracara inhabits the Falkland Islands and Tierra del Fuego, just off the coast of the southernmost tip of South America. Taxonomy ...

Caracara Creightoni
The Bahaman caracara (''Caracara creightoni''), also known as Creighton's caracara, is an extinct bird of prey. It is known only from a few fossils discovered in the Bahamas and Cuba.Tumas, Alejandro; Hobbs, Amanda (August 2010), Todhunter, Andrew, ed., "Blue Holes of the Bahamas" in "Deep Dark Secrets", ''National Geographic'' 218 (2): insert. ''Caracara creightoni'' was a scavenger and opportunistic species instead of a predator like its sister extant species (''C. plancus''). It lived during the late Pleistocene to the beginning of the Holocene era. ''C. creightoni'' stood 58 cm tall, was short-winged and likely a poor flier. This species went extinct as a result of humans arriving on its home islands and wiping out the bird's prey species. A 2,500 year old ''C. creightoni'' femur from an Abaco Islands blue hole yielded a nearly complete mitochondrial genome. The DNA shows that the species was closely related to the crested caracara The crested caracara (''Caracara plancus'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bird Genera
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. Bi ...

Caracara Tellustris
The Jamaican caracara (''Caracara tellustris'') is a prehistoric species of terrestrial bird in the falcon family, Falconidae. It was native to the island of Jamaica in the Caribbean, where it probably inhabited dry forests in the island's south during the early Holocene. This species was described based on fossils discovered in the Skeleton Cave in the Jackson's Bay Cave system on the south coast of Portland Ridge. Description ''Caracara tellustris'' was large and had diminished wings; it was probably mostly terrestrial and may have been flightless. It probably had a lifestyle similar to that of the secretary bird of Africa. It likely became extinct following Paleo-Indian colonization of the island during the Quaternary extinction event, but it may have survived up to European colonization of the island, after which habitat destruction and invasive species An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms it ...

San Miguel Island
San Miguel Island (Chumash: ''Tuqan'') is the westernmost of California's Channel Islands, located across the Santa Barbara Channel in the Pacific Ocean, within Santa Barbara County, California. San Miguel is the sixth-largest of the eight Channel Islands at , including offshore islands and rocks. Prince Island, off the northeastern coast, measures in area. The island, at its farthest extent, is long and wide. San Miguel Island is part of Channel Islands National Park, and almost all of the island () has also been designated as an archaeological district on the National Register of Historic Places. This westernmost Channel Island receives northwesterly winds and severe weather from the open ocean. The cold and nutrient-rich water surrounding the island is home to a diverse array of sea life that is not found on the southern islands. San Miguel Island, together with numerous small islets around it, is defined by the United States Census Bureau as Block 3010, Block Group 3, ...
